The Correlations Between Some Elements Levels in Some Biological Samples with Different Post Mortem Periods in Experimental Animalse

Abstract

In this study two groups of swiss albino rats were used, one group as control, while the others were exposed to n1echanical brain trauma, drowning, asphyxia and fraction dislocation of cervical vertebra.

Iron (Fe), Zinc (Zn), Copper (Cu), Selenium (Se), and magnesium (Mg) were determined in brain, heart, liver, kidney, lung, muscle and bone using energy dispersive X-ray fluorescence analysis (EDXRF) and neutron activation analysis, whereas, the results were statistically compared with controls.

There were significant changes in the levels of certain elements in each organ according to the causing of death.

The occurring changes could be explained by the effect of stress factor resulting frmn the accident were exposed to it and/or the accompanying metabolic changes due to the necrotic tissues, as well as, probably resulted from defense strategies of organisms and induced by the hormone like substances.
